More than 30 Tajik nationals have been stranded at Moscow's Vnukovo airport since last week amid tightened passport controls almost three months after a deadly terror attack near Moscow. Some of the stranded Tajiks told RFE/RL that Russian security officials did not allow them to enter the country, saying that "Tajiks cause problems in Russia." In April, thousands of Tajiks were stranded in Moscow airports after they were barred from entering Russia amid anti-Tajik sentiments after 11 Tajik men were arrested for their alleged involvement in the attack on a concert hall near Moscow in March that left 144 people dead.
